79 nautique rebuild

The #6 spark plug, didn't #6 have something to do with fuel pump installation?

Late start this morning, hooking up now, boat ride time, my buddy asked if i had sea tow, he knows i do, then said bring an anchor and a paddle. 

Forgot to mention before i set the timing to 11 it was pulling 15-16 vacuum

Sea trial, it started and idled down nice, nothing seemed out of place and as far as i can see the packing gland nut is so loose the drip is coming out between the threads instead of out of the front of the nut.

admittedly i was skeptical but like captain ron said, "if anythings gonna happen, it'll happen out there"

it didn't sink, didn't leak, didn't blow off any hoses and after an idle stop screw and shift link adjustment

it idles in gear nice, definitely catching f-n-r correctly, making temp oil pressure and charging.


after a half hour of back and forth (in the channel, next to the spoil islands right off christiansons landing grant fl.) at and under 3000 rpm, couldn't resist the temptation and cracked it open.

i was dumbfounded how fast it went, with that 4blade o.j. figured 40 and i'd be happy.

so had to check the gps and fire up the other camera for an up/down wind short run.


this week is fluid changes alignment re check, once over the whole thing and more test runs.

the things a pleasure to tow launch load and run. No issues docking and it was windy and choppy.

Video sound is crappy, no idea what for. There is a hard acceleration towards the end and also thanks to everyone who had advice tech help and kept me going on this. Still more tinkereing but got some faith now she'll come back real well.

I was very surprised at the 48, thought they were a 44 mile an hour boat and was looking for a 40-42 at this point. Test rides from here on out will stay around the 3-3500 mark.

Steering torque is non existent at any speed, non to the left, and a touch half way thru a right turn, granted the turns were done in the 20's and not sharp or hard, i see no reason to push it.

no reason to play with the trim tab and 99% sure i won't try to align the wheel since load wind tide etc plays a part. Right now theres even +/- rudder in both directions.

At this time i will retract (at least in part) my comments on the sucky trailer, it isn't too high, it loads/launches good and of course my modifications make it that much better. 

Wrap up parts on order or at least i hope it's the wrap up parts.

It is rustoleum, 7727. The outline or shadow is rustoleum gloss black.

I'll call customer service in the morning and hopefully get some answers.

No rain thru thursday but if it has to sit till next week so be it.

I slapped the registration on it at the ramp the day of the first test ride.

They'll have to get pulled for the last wet sand and wax.

Want a good laugh ? Look what i found !

My windows in the dining room go all the way to the floor, 1959 jalhousie's original to the house.

I sweep every day, vacuum couple times a week, i don't always open the blinds but today on the floor in the corner of the front window laying in the grout line was this, wouldn't be surprised if it was the culprit pouring gas down the primaries but not real sure which side of the carb it's from.

Umm...............what are you doing losing carburetor parts in the dining room?

That your accelerator pump transfer tube, there's only one on your 4160 and it's on the primary metering block.(or at least it would be if you didn't lose it )  

Earlier 4160's had an orifice and a different gasket between the metering block and the body instead of this tube..

In your carburetor, with that not installed you have a huge unmetered internal opening and the engine runs crazy rich, so I'd figure that was your problem

If you can bump it into gear at your desired RPM and have a slight drop in RPM (like around 50 or so) and idle around like that and if you can after idling like that, accelerate quickly and take off with no hesitation, things sound pretty good. Your accelerator pump supplies a shot to help here too.

If you're happy (and not curious) about the way it runs with things the way they are, you could leave it alone..............or you could note your settings on the mixture and speed screws and open the mixture screws and follow the video.

So.................I figure there'll be an update with how it is after your adjustments 

PS    All this is really saying is that you may be idling on the transition slots with fuel from the idle and main circuits and not on the idle circuit only

Agreed.  It clearly shows your priorities.  My wife gets pi$$ed when I put engine parts in the dishwasher for deep cleaning.  She hasn’t yet caught the vision.
